4 Claims.

The purpose of this invention is to provide an improved baffling devicethat may be inserted in a pipe stem, cigarette or cigar holder, or thelike,

, which cools the smoke materially before it is 5 drawn into the mouth,which also condenses and traps the nicotine contained in the smoke, and

which may be readily cleaned.

The invention is a bailling device having a continuous spiral passagetherethrough which is formed in three separable parts, and which mayreadily be inserted in a pipe stern or in a cigar or cigarette holder orin any device through which smoke or the like may be drawn.

Many types of baffling devices have been provided for pipes and thelike, but these either reach a saturation point or are diiiicult toclean or are too expensive or elaborate for normal use and, therefore,it has been found desirable to provide a simple and eiiicient bafflingdevice made of a minimum number of parts, in which the parts may readilybe separated for cleaning.

The object of the invention is, therefore, to provide a baiing devicethat may be inserted in the stem of a pipe or the like, which may bemade of metal or other material that will notf absorb nicotine andmoisture, and from which the nicotine may readily be cleaned.

Another object is to provide an arrestingdevice adapted to be insertedin the stern of a pipe ,.0 or the like, which is made of several parts,and

in which the parts may readily be opened for cleaning and also readilyassembled.

Another object is to provide a cooling device for the smoke from a pipeor the like, which may 35 be insertedY in the stem, and which will alsoarrest nicotine.

Another object is to provide a baiing device for pipe stems and thelike, which may readily be inserted in an opening in the stem, and whichis adapted to hold the two sections of the stem together.

A further object is to provide a baiiling device adapted to be heldinpipe stems'and the like, having a spiral passage therethrough, in whichthe entrance end of the passage is elevated, preventing moisture passingtherein.

And4 a still further object is to provide a battling device for pipes,cigar and cigarette holders, and similar devices, which cools the smoke,and arrests the nicotine, which is of a simple and economicalconstruction.

With these ends in view the invention embodies a device formed in twosemi-circular sections, having a cylindrical core, a spiral passageextending around the core, and opening at the opposite ends, and alsospiral grooves in the outer surface.

Other features and advantages of the invention will appear from thefollowing description, taken in connection with the drawing, wherein:

Figure i is a view showing a pipe with the device inserted therein withpart of the pipe broken away, showing the baffling device.

Figure 2 is a cigar or cigarette holder with part broken away, showingthe device incorporated therein.

Figure 3 is a longitudinal section through the device with the coreshown in full lines.

Figure 4 is a view looking upward toward the under side 'of the upperhalf of the device.

Figure 5 is a similar View looking downward upon the lower half of thedevice.

Figure 6 is a side elevation on an enlarged scale showing an alternatedesign in which the grooves at the outer surface are illustratedopposite hand to those shown in Figures 1 and 2, and' also having partbroken away, showing the interior thereof.

Figure 7 is a view looking toward the end of the device that ispositioned toward the bowl of the pipe.

Figure 8 is a cross section through the device with the three partsseparated.

Figure 9 is a View similar to that shown in Figure 7 looking toward theopposite end of the device, showing an alternate design, in which theouter surface is formed with flat sides.

In the drawing the device is shown as it may be made, wherein numeral lindicates the upper half, `numeral 2 the lower half, and numeral 3 thecore.

Each of the halves l and 2 are in the form of a half-cylinder, as shownin Figure 8, and each is provided with the complementary parts of aspiral groove with the, part in the upper half indicated by the numeralli, and that in the lower half by the numeral 5. The webs ii and 'iloetween the grooves are formed with semi-circular openings 3 and 9, asshown in Figure S, and these are curved to correspond with the outersurface of the core 3, which is in the form of a round rod extendingthrough the device, as shown in Figure 3.

The pipe end of the device, which is indicated by the numeral i9, isprovided with an opening il extending upward in the upper part I, andthis communicates with the groove 4 as shown in Figure 3, and the lowerhalf is also provided with an opening I2 similar to the opening l l, andpositioned at the opposite end of the device, and

this opening communicates with the opposite end of the groove 4, therebyproviding a complete passage through the device passing in through theopening ll, through the spiral groove, and out of the opening l2. Theouter surface of the device is provided with a spiral thread indicatedby the numeral I3 in the upper part, and I4 in the lower part. Thisgroove may be of any pitch, size, or design and may be relatively small,or large, as may be desired.

It will also be understood that the groove 4 may be rectangular asshown, or of any shape or design. The outer surface of the device mayalso be round as shown in Figures l to 8, or may be formed with aplurality of at sides l5 as shown in Figure 9, in which the upper halfof the device is indicated by the numeral I6, and the lower half by thenumeral l'l.

It will be understood that other changes may be made without departingfrom the spirit'of the invention. One of these changes may be in therelative size of the device, as it may be made relatively small indiameter as compared with the length, or relatively short, and it willalso be understood that it may or may not be used as a means for joiningthe stem to the pipe, or for holding the two parts together. Anotherchange may be in the use of other means in the outer surface for holdingthe device in the pipe stem or holder, and still another may be in theuse of other means for locking and holding the two parts together.

The construction will be readily understood from the foregoingdescription. In use the device may be made and supplied with the pipe,or provided as a separate unit, and the pipe and stem may be providedwith openings corresponding with the outside diameter of the baiiiingdevice so that, with the parts of the baffle assembled they may bepressed into the pipe, and then the stem maybe pressed over the oppositeend, as shown in Figure 1, so that the device provides means forsecuring the pipe and stem together. It will be'noted that the end withthe upper opening is inserted in the pipe portion of the device, therebypreventing saliva ilowing through the device into the pipe bowl and alsofacilitating arresting nicotine from the bowl of the pipe.

It will also be noted that as it is necessary for all smoke to passthrough the spiral passage, it will have a tendency to cool before itreaches the mouth, and in passing through this continuous passage the'nicotine will be deposited in the parts thereof, so that smoke enteringthe mouth will be substantially cool, and also substantially free ofnicotine. Making the device in three separate parts makes it possible totake it apart and easily clean each part. The threads in the outersurface provide gripping means by which it may readily be held and itwill be understood that the outer surface may be roughened by any means.
